Research and development over the past four decades has lead to significant advances in the field of Digital Signal Processing. A single textbook covering the basics of linear continuous-time and discrete-time systems and their applications along with MATLAB programs is the need of the day. The authors have made a sincere attempt to meet these requirements.

The authors have developed this book from their lecture notes prepared for teaching the undergraduate- and postgraduate-level courses over the past several years. This book is suitable as a text for two subjects–Signals and Systems, and Digital Signal Processing in BE, AMIE and Grade IETE degree programs, and for the subject Advanced Digital Signal Processing in the ME degree program. It will also serve as a useful reference to those preparing for competitive examinations.

The various concepts of the subject are arranged logically and explained in a simple reader-friendly language. For proper understanding of the subject, a large number of problems with their step-by-step solutions are provided for every concept. Illustrative examples are discussed to emphasize the conceptual clarity thereby presenting typical applications. Solutions to university problems have been included in many of the chapters in this edition. A set of questions and exercises at the end of each chapter will help the readers test their understanding of the subject.

Student’s Center contains a sample chapter on MATLAB Programs and some useful topics selected from the book. This would give you the flavor of the published book.

The Instructor’s Center provides instructors with Solution Manual and PowerPoint Slides.
